The following describes the production method of twisted pair in several application environments. The
MDI indicates that this port is a level connection, while MDI-X indicates that this port is an ordinary port. The
1) When a network device such as a PC is connected to the HUB, the network cable is a straight-through cable. The two ends of the twisted-pair cable must be in one-to-one correspondence. In this case, the HUB is MDI-X and the PC is MDI. 10Mbps network cable as long as the two ends of the twisted pair can be, do not have to consider the order of different colors of the line, and if you use the 100M rate connected, you must strictly follow the EIA/TIA568A or 568B cabling standards. The
2) During the inter-HUB cascade connection, the level connection control switch should be placed on the MDI (Uplink) and connected with the straight line at the same time. If HUB does not have a dedicated level connection, or cannot use a level connection, MDI-X ports must be used to connect. At this time, we can use the crossover line to achieve the purpose. The crossover line here is to use one end RJ when doing the network cable. Pin 1 of the -45plug is connected to pin 3 of the other end of the RJ-45 plug; then pin 2 of the other end of the RJ-45 plug is connected to pin 6 of the other end of the RJ-45 plug. The following chromatograms can be made: A: orange, orange, green, white, blue, blue and white, green, brown, brown; B: green, white, green, orange, blue, blue and white, orange, brown, Brown.
